Study on estimation model of increased operation costs of urban sewage treatment plant upgrading
Recently,provinces and cities across the country have successively issued stricter wastewater discharge standards,and some wastewater treatment plants have been upgraded.Aiming at the problem of increased operating costs from the upgrading work,this paper establishes a calcula-tion model for increased operating costs after the sewage treatment plant is rebuilt,and performs a verification analysis based on the example of the sewage plant.The research results show that the model can well reflect the mathematical relationship between the increase in operating costs and the indicators of urban sewage treatment plants after upgrading and reconstruction,and can be used to simulate new operating expenses after upgrading,and it may provide technical support for the existing sewage treatment plant upgrading and daily operation management after the transformation.
